Abstract: PURPOSE:To prevent the displacement of a focal position of a lens by constituting the titled device so that a lens part is separated from and allowed to approach a semiconductor laser, based on a temperature change, by an annular projecting part formed as one body on the outside peripheral part of collimating lens made of plastic. CONSTITUTION:A semiconductor laser 2 is fixed to one end of a fixed cylinder 1, a collimating lens 3 made of plastic is provided on the inside, and an annular projecting part 4 is formed as one body on the outer circumferential part of the lens 3.

Title: Device for charging optical fiber into pipe
Inventor: YABUKI YOICHI
IPC: G02B6/44
Filed: 1986-11-17
Abstract: PURPOSE:To surely send an optical fiber into a pipe end without damaging the fiber by arranging a vibration proofing guide having a taper or an R part at the end on the same axis as the pipe end into which an optical fiber is inserted close to the pipe end. CONSTITUTION:When spiral vibration is imparted to a copper pipe roll R through a shaking table 2, the optical fiber 6 supplied from the pipe end 7 at the lower part of the roll is continuously sent into a steel pipe P by the transporting force of the vibration. Namely, the optical fiber 6 is veered out from a spool 13, and moved successively through the spool 13, a holding guide 12, a detector 11, the vibration proofing guide 10, a pipe inlet end 7, the pipe P of the roll, and a pipe terminal end 8 by the vibration of the roll R. The optical fiber is thus charged into the whole roll after a specified time. Although the optical fiber 6 veered out from the spool 13 moves toward the pipe end 7 through the vibration proofing guide 10, the deflection of the fiber to the outside of the pipe end 7 is controlled by the vibration proofing guide 10. Accordingly, the optical fiber is not damaged, the vibrational transfer of the fiber is not counteracted, and the excellent transfer condition can be maintained.
